How to Kill Moss With Vinegar

Moss causes surface decay.

Moss thrives in moist, shady environments, especially during cool weather. On pathways, roofs and other surfaces, moss is an issue because it can slowly cause surface decay. It is also slippery, which can pose as a safety hazard. In the landscape, moss can prevent water from reaching roots of nearby plants, grass, trees and shrubs. Vinegar is a natural, effective plant killer. It works well on moss to kill it so its removal is easier. Once you're rid of the moss, make some changes, such as pruning nearby trees to increase sunlight so that the moss does not return.

1

Spray the moss liberally with household white vinegar until it is thoroughly soaked. Do this on a dry, cloudy day when temperatures are above 65 degrees Fahrenheit.

2

Wait at least 10 minutes. Then, scrub the moss off the surface. This process varies depending on where the moss is growing. A hard-bristled scrub brush works well, as does a straight dull scraper.

3

Rinse the area with a hard stream from your garden hose, and repeat the vinegar and scrubbing after the area dries, if necessary. Try a higher concentrate vinegar, such as one that contains 20 percent acetic acid, or chlorine bleach if the household vinegar is not working.
